AWS Integration Prerequisites

This topic explains how to prepare for Lacework integration from the AWS console.

If you plan to use Terraform, see Integrate Lacework with AWS.

If you plan to use CloudFormation, see AWS Integration Using CloudFormation.

Prerequisites

Before you can integrate your AWS cloud environment with Lacework, you must configure the following for compliance and CloudTrail monitoring with Lacework:

  • SNS topic - Amazon Simple Notification Service (SNS) topic is a logical access point that acts as a communication channel. A topic lets you group multiple endpoints (such as AWS , Amazon SQS, HTTP/S, or an email address). An SNS topic is required for all CloudTrail integrations. Lacework can use an existing SNS topic or create one if you have not added an SNS topic to an existing CloudTrail.
  • SQS queue - Amazon Simple Queue Service (SQS) is a message queue service used by distributed applications to exchange messages through a polling model, and can be used to decouple sending and receiving components—without requiring each component to be concurrently available. Using Amazon SNS and Amazon SQS together, messages can be delivered to applications that require immediate notification of an event, and also persisted in an Amazon SQS queue for other applications to process at a later time. An SQS queue is required for all AWS CloudTrail integrations monitored by Lacework.
  • S3 bucket - A bucket is a container for objects stored in Amazon S3. An S3 bucket is required for all CloudTrail integrations. Lacework can use an existing bucket or create a new bucket in the designated account.
  • CloudTrail - AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational and risk auditing of your AWS account. Actions taken by a user, role, or an AWS service are recorded as events in CloudTrail. Lacework can create a new trail or use an existing CloudTrail.
  • IAM cross-account role - A cross-account role is required to give Lacework access for assessments of cloud resource configurations and for analysis of CloudTrail events. The cross-account role is given the following policies:
    • SecurityAudit - AWS Managed Policy to provide read-only access to cloud resource configurations.
    • Lacework custom audit policy - A custom policy that extends SecurityAudit to enable read-only access to additional configuration resources.
    • Lacework custom IAM policy - A custom policy that provides Lacework read-only access to ingest CloudTrail logs.

Additional requirements:

  • AWS Account Admin - The account used must have administrative privileges for every AWS account that you want to integrate with Lacework.
  • Lacework Administrator - You must have a Lacework account with administrator privileges.

Overview

Lacework supports three pipelines to integrate with AWS:

  1. CloudTrail Log Delivery Notifications
  2. S3 Event Notifications
  3. S3 Event Notifications with SNS
note
  • The pipeline design depends on your current environment and your future design goals.
  • As long as the data arrives at Lacework, your pipeline design choices are up to you.
  • For example, if your SNS topic is in a separate AWS account, you can use the option of not using SNS.
  • In another use case, if your existing S3 bucket is already sending messages to your existing SQS queue. The new S3 to SQS notification setup (for Lacework) is not possible because both notifications require the same suffix (not allowed by AWS). In this case, you can move to an SNS fanout.

CloudTrail Log Delivery Notifications

The following diagram shows a simple presentation of the AWS integration using CloudTrail SNS notifications.

aws-integration-using-sns

1. Create an SNS Topic

An SNS topic is a communication channel for SQS queue messaging from your AWS environment to Lacework.

If you already have an SNS topic for integration, copy or record the Amazon Resource Name (ARN) for the topic. If you do not have an SNS topic, use the following steps to create one.

  1. Log in to your AWS account.

  2. Go to the Amazon Simple Notification Service page.

  3. Click Next step to create a new SNS topic.

  4. Select the Standard type of topic.

    create-standard-sns-topic

  5. Enter a name and display name for the new topic.

  6. Click Create topic. Details of the new SNS topics appear, along with the ARN for the topic.

  7. Copy or record the ARN for the new topic. You will need this information when you configure integration from the Lacework Console.

    arn-sns-topic

2. Configure the Access Policy for your SNS Topic

  1. Select the Access policy tab for your SNS topic.

  2. Click the Edit option.

  3. Copy the following code snippet and replace the existing policy code block (using the ARN you just recorded):

    {
    "Version": "2012-10-17",
    "Statement": [
    {
    "Sid": "AWSCloudTrailSNSPolicy20131101",
    "Effect": "Allow",
    "Principal": {
    "Service": "cloudtrail.amazonaws.com"
    },
    "Action": "SNS:Publish",
    "Resource": "<ARN_of_SNS_Topic>"
    }
    ]
    }

  4. Click Save.

By default, the topic owner has permissions to publish the topic. To enable other users or applications to publish to the topic, you should use AWS Identity and Access Management (IAM) to give publish permission to the topic. For more information about giving permissions for Amazon SNS actions to IAM users, see Using identity-based policies with Amazon SNS.

3. Set Up CloudTrail SNS Delivery

1. Create an S3 Bucket

S3 Event Notifications with SNS

The following diagram shows a simple presentation of the AWS integration with S3 event notifications and SNS.

s3-notifications-using-sns

1. Create an SNS Topic

An SNS topic is a communication channel for SQS queue messaging from your AWS environment to Lacework.

If you already have an SNS topic for integration, copy or record the Amazon Resource Name (ARN) for the topic. If you do not have an SNS topic, follow the steps mentioned in 1. Create an SNS Topic to create one.

2. Set Up the SQS Queue

See 4. Set Up the SQS Queue.

3. Set Up the SNS Topic To Receive Notifications From the S3 Bucket

You must grant the Amazon S3 principal the necessary permissions to call the relevant API to publish messages to an SNS topic. This is so that Amazon S3 can publish event notification messages to a destination.

The following is an example of an AWS Identity and Access Management (IAM) policy that you attach to the destination SNS topic.

{
"Version": "2012-10-17",
"Id": "example-ID",
"Statement": [
{
"Sid": "Example SNS topic policy",
"Effect": "Allow",
"Principal": {
"Service": "s3.amazonaws.com"
},
"Action": [
"SNS:Publish"
],
"Resource": "SNS-topic-ARN",
"Condition": {
"ArnLike": {
"aws:SourceArn": "arn:aws:s3:*:*:bucket-name"
},
"StringEquals": {
"aws:SourceAccount": "bucket-owner-account-id"
}
}
}
]
}

For more information, see Granting permissions to publish event notification messages to a destination.

4. Enable and Configure Event Notifications Using the Amazon S3 Console

You can enable certain Amazon S3 bucket events to send a notification message to a destination whenever those events occur.

  1. Sign in to the AWS Management Console and open the Amazon S3 console.

  2. In the Buckets list, choose the name of the bucket that you want to enable events for.

  3. Choose Properties.

  4. Navigate to the Event Notifications section and choose Create event notification.

  5. In the General configuration section, specify a descriptive event name for your event notification. Optionally, you can also specify a prefix and a suffix to limit the notifications to objects with keys ending in the specified characters.

    a. Enter a description for the Event name. If you don't enter a name, a globally unique identifier (GUID) is generated and used for the name.
    b. (Optional) To filter event notifications by prefix, enter a Prefix.
    For example, you can set up a prefix filter so that you receive notifications only when files are added to a specific folder (for example, AWSLogs/).
    c. (Optional) To filter event notifications by suffix, enter a Suffix.

  6. In the Event types section, select s3:ObjectCreated:*. s3-config.png

  7. In the Destination section, choose the event notification destination.

    a. Select the destination type as SNS Topic.
    b. After you choose your destination type, choose a topic from the list.
    c. Or, if you prefer to specify an Amazon Resource Name (ARN), select Enter SNS topic ARN and enter the ARN.

  8. Choose Save changes, and Amazon S3 sends a test message to the event notification destination.

5. Subscribe the SQS Queue to the SNS Topic

You can subscribe one or more SQS queues to an SNS topic. When you publish a message to a topic, the SNS sends the message to each of the subscribed queues. Amazon SQS manages the subscription and any necessary permissions. See Subscribing an Amazon SQS queue to an Amazon SNS topic (console).

6. Create IAM Policies

See 5. Create IAM Policies.
